79fcb6dec3 Changed the TableGen created MatchInstructionImpl() setting of ErrorInfo.
The algorithm for identifying which operand is invalid will now always point to
some operand and not the mnemonic sometimes.  The change is now that ErrorInfo
is the index of the highest operand that does not match for any of the matching
mnemonics records.  And no longer the ~0U value when the mnemonic matches and
not every record with a matching mnemonic has the same mismatching operand
index.

9d7f011110 [AVX] Implement EnforceSmallerThan for mixed int/fp type lists. This
makes type checking for extract_subvector and insert_subvector more
robust and will allow stricter typechecking of more patterns in the
future.

This change handles int and fp as disjoint sets so that it will
enforce integer types to be smaller than the largest integer type and
fp types to be smaller than the largest fp type.  There is no attempt
to check type sizes across the int/fp sets.

a49c7dfb36 Improve the AsmMatcher's ability to handle suboperands.
When an operand class is defined with MIOperandInfo set to a list of
suboperands, the AsmMatcher has so far required that operand to also define
a custom ParserMatchClass, and InstAlias patterns have not been able to
set the individual suboperands separately.  This patch removes both of those
restrictions.  If a "compound" operand does not override the default
ParserMatchClass, then the AsmMatcher will now parse its suboperands
separately.  If an InstAlias operand has the same class as the corresponding
compound operand, then it will be handled as before; but if that check fails,
TableGen will now try to match up a sequence of InstAlias operands with the
corresponding suboperands.

6cd0b17ba7 When matching asm operands, always try to match the most restricted type first.
Unfortunately, while this is the "right" thing to do, it breaks some ARM
asm parsing tests because MemMode5 and ThumbMemModeReg are ambiguous.  This
is tricky to resolve since neither is a subset of the other.

XFAIL the test for now.  The old way was broken in other ways, just ways
we didn't happen to be testing, and our ARM asm parsing is going to require
significant revisiting at a later point anyways.

dc1a2bd3aa Fix some tablegen issues to allow using zero_reg for InstAlias definitions.
This is needed to allow an InstAlias for an instruction with an "OptionalDef"
result register (like ARM's cc_out) where you want to set the optional register
to reg0.

e4e5e2aae7 Add support to the ARM MC infrastructure to support mcr and friends. This requires supporting
the symbolic immediate names used for these instructions, fixing their pretty-printers, and
adding proper encoding information for them.

With this, we can properly pretty-print and encode assembly like:
	mrc p15, #0, r3, c13, c0, #3

Fixes <rdar://problem/8857858>.

7597212abc Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.
